CANADA, ASSIGNOR OF ONE-FIFTH T0 NONSINKABLE SHIP.

Application led June 22,

This invention relates to a new and useful device in the nature of a non-sinkable ship, comprising pontoons attached thereto, and a meansof lowering the said pontoons during rough weather or a heavy sea, so as to prevent the sinking or capsizing of the ship.

The object of the invention is to provide a non-sinkable ship of novel construction and arrangement of parts, hereinafter more fully described, claimed, and illustrated in the accompanying drawings.

Fig. 1 is a side elevational view of a non sinkable ship constructed according to this invention.

Fig. 2 is a Vfront elevational view thereof, showing the pontoons in a raised position.

Fig. 3 is a similar view showing the pontoons in a lowered or in use position.

Fig. 4 is an enlarged fragmentary sectional View, taken on the line4-4 of Fig. 5.

. Fig. 5 is a top plan `view of my improved non-sinkable ship- Fig. 6 is an enlarged fragmentary sectional view, taken on the line 66 of Fig. 5.

Fig. 7 is a fragmentary view similarto Fig. 4 but illustrating a modification of the invention.

As here embodied my improved non-.sinkable ship comprises a ship 10 of any desired tonnage, such as ordinarily used for passengers 0r freight, preferably of the ocean gcing type, and equipped with pontoons 11 and 12 of hollow construction and of air-tight structure. The pontoons 11 Vand 12 are hingedly mounted to the sides of the ship 10 by rods 13 and brackets 13 so as to be positioned in proximity to the water line of the ship and extending longitudinally and parallel to the ship. y

Link members 14 are pivotally arranged on rods 15 secured to brackets 15 attached to the outer edges of the pontoons, and also pivotally connected to rod 16, andto 'other link members 17, pivotally connected to rods 18 secured to brackets 18 attached to the sides of the ship. rFhe flexiblemembers 19 and 20 are secured to rods 15 and extend over the guide pulleys 21, secured to the shafts 23 rotatively mounted in the brackets 24 attached to the deck of the ship 10. The flexible members 19 and 2O engage onto drums 22`attached to the rod 21 rotatively mounted on the brackets 22 attached to the deck of the ship.

Several towers project from the ship 10,

1927. seriai No. 200,569.

and these towers consist of vertical rods 24 joined at their top ends by plates 25. Slide `members 26 are arranf'red between the rods and to drums 3() rotatablymounted to plates 31 attached to rods 24.- Gears 32 and 33 connect the drums to receive rotation from the shaft 21. The vbottom ends of rods 24 areV connected to plates 34, and brackets35 attachY the plates to the boat 10.

The boat 10 is provided with apropeller 36-on a driver shaft 37 having a bevel gear 38 meshing with another bevel gear39 on` shaft 40 supported by bracket 41.A The` shaft 40 is provided with a clutch arrange ment 42, and a second bevel gear 43 on shaft 40 meshes with a `gear 44 on kshaft 45 connected with a gear speed reduction mech# anism in boX'46, which also connects with shaft 21. yA lever 46 projects from the boX 46 and connects with the gears within the boXso that by movement ofthe lever, thegears move to reverse the drive connection with shaft 21. YA large link 47 is inserted through the front of the boat, 'and small links 48 connect the ends of the large link to the pontoons. 'Chains' 49 are connected at theirlower endstothe rods 13 and are pron vided with hooks 50 at their upper ends, normally engaged on pins 51 projecting from the side of the ship. Hooks 52 are pivotally arranged on rods 18 and engage rods 1.5 to hold the pontoons in raised position. Vacuum pumps 53 are mounted on the ship, andflexible hoses 54 therefrom with check valves 55 connect to the pontoons. Plates ,5G reinforce the boat 10 at points where stresses are obtained due to the various apparatus mounted'on the sides of the boat.

VThe-operation of the device consists in normally arranging theV pontoons in Araised position shown in Figs. 1, 2, and 5. The air Vfrom within the pontoonsmay bewithdrawn to make them more buoyant. The pontoons may be lowered by releasing hooks 52 from rods 15, moving lever 46" to cause shaft 21 to turn anti clockwise as seen looking at Fig. 2, and moving clutch 42 so that rotation from the driver shaft 37 is communicated to shaft 21. Gears 32, 33 communicatethis rods 28,

rotation to drum and flexible member 29 winds onto lthis drum, drawing slide 2.6V

downwardly, forcing, rods 28 to more .the Pontoons to the lower position Shown in Fig. Drums 22 on shaft 2 turn leaving flexible members 19 and 20 slack to permit this operation. Then the pontoons the lowered position the clutch 42 is disengaged. The hooks 5.() are disengaged from the pins 51 and engaged onto rods 16 to hold the pontoons in lowered position. The pontoons may be raised by niovino" control 416. to causer shaft 21/ to turn clociqwise as seen looking 2. The drums 22 draw the flexible members l2, 2.() to raise the pgmtoons, while drums 80 allow the flexible members 2 9 to be slack and permit the said raising .of the pontoons.

The modification .of the invention illustrated in Fig. 7L discloses a means for adjustine' the Vupper rends of rods 28 so as to change the normal positions of the pontoons. rlhe slide 2.6 has projecting' portions2El and a plurality .of tongues 2.6". Auxiliaryslide mllbels 5.8 have fone of their ends .engaged in grooves 59 and their other ends are pivotally connected to theV 4upper .ends of rods 28;. Screws 60 are rotatively arranged in the tongues 2G?, and held againstfdis.

placement by plates 6l attached to the bot* tolli of portions 2.6a ,and 26h, and these screws threadedly engage .the auxiliary slides 58. The ends of the VScrews are equipped ,with lool; nuts `62 to normally lock the screws from turning. The screw may be turned to cause the auxiliary slides to move therealong, and change the position lof V.the

v,While I have illustrated and described the preferred form, construction, and arrangement of the several Aelements employed, it will be understood that the device is, nevertheless, susceptible of considerable modication therein, and I have therefore reserved the privilege of resorting),` to all such changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus described my invention what I claim `as new and desire to secure by Letyters ,l-{atentl o f the United States is as folbeing pivotally arranged on the last mentioned rods, flexible members secured to `the first mentioned rods, and provided with ineens for drain- 11s er Slekenes theseleX- ible members, towers projecting from the ship, slides arranged on the towers, connecting Iloyers arranged between the slides and the first mentioned rods, flexible members secured to the slides and provided with means for drawing or slackening these flexiblemembers.

2. In combination with a ship, pontoons hingedly mounted to the sides of the ship in proximity to the water line of the ship, rods secured on the pontoons on the sides remote from the ship, linlr members pivoted to the rods, other vrods secured through free ends .of the link members, other link members .connected to the second menthe tioned rods, still other rods secured to f Vmembers secured to the first mentioned rods,

anc provided with meansv for Vdrawing or slaclrening these fiexible members, towers projecting from the ship, slides arranged on the towers, connecting` levers` arranged between the slides, and the first mentioned rods, flexible members secured to the slides and provided with means for drawing or slackening` these flexible members. 8. In combination with a ship, pontoons hingedly mounted .to the sides of the vship in proximity to the water line of the ship, rods secured on the pontoons yon the sides remote from the ship, link members pivoted to the rods, other rods secured through the free ends of the link members, vother link members ,connected to the second mentioned rods, still other rods secured to the sides of the ship, and the free .ends of tliesecond mentioned link members being pivotally arranged on the last mentioned rods, iiexible members secured to the first mentioned rods, and provided with means for drawingor slaclrening these flexible members, towers projecting from the ship, and consisting of vertical rods joined atV their top `,ends plates, slides arranged between the said vertical rods, connecting levers Varranged between the slides and the first mentioned rods, flexible members secured to .the slides and provided with means for drawing or slackening these `flexible members.

In testimony whereof I have affixed my signature.
